People in general are lazy about finding what is truth. With this they go to one source, maybe less commonly to two sources, to find what is truth from that which they would take. Of course it has to be a source they came to really trust for that. For any more reliable way of finding what is truth, that is more responsibility that those lazy about it will not do, it will take more research to find what can be learned from a lot of sources, and not dismissing those more qualified in the area for where what is truth might be learned, while yet considering as much as possible from what can be learned. How many do that? It seems those ones are rare.
